SYSTEM SOLUTION Jan/2007 SYSTEM SOLUTION DVB-T Front-end Reference Design Freescale Semiconductor and Micronas offer a joint DVB-T front-end reference design. Built around the Freescale MC44S803 MC44S803 CMOS silicon tuner and Micronas' DRX 3978D 3978D COFDM demodulator, the reference design offers a step forward in DVB-T reception performance, power consumption and system cost reduction. Both the silicon tuner and the COFDM demodulator are especially designed to exceed all relevant DVB-T receiver specifications, including the NorDig-Unified v1.0.2 and DTG specifications. Freescale MC44S803 MC44S803 Features Single-chip CMOS broadband tuner: 48 - 861 MHz RF input Wide gain control range: >80 dB AGC range Very low noise figure: 7.5 dB Evaluation Kit The Freescale tuner and Micronas' demodulator control software has been combined into a single, easy-to-use driver software. The evaluation kit consists of: Low power consumption: 700 mW typical Motherboard and daughter card with MC44S803 MC44S803 and DRX 3978D 3978D QFN64 QFN64 package (9 × 9 mm2) PC parallel port connector Micronas DRX 3978D 3978D Features PC control software tool Schematics High-quality PLL and flexible clock options enable re-use of MC44S803 MC44S803 clock output Pre-SAW sense input for optimal RF-AGC settings Fixed 7.4 MHz SAW filter operation Superior digital and adjacent channel performance Impulsive noise cruncher Small footprint: QFN48 QFN48 package (7 × 7 mm2) Gerber files, PCB design files Bill-of-material (BOM) Driver user guide, including source code The DVB-T reference design can be ordered at both Micronas and Freescale.
